python - 尝试使用 pandas 读取 excel 并将它们添加为 Pysolar/Solar 上的记录但得到 TypeError: a bytes-like object is required, not 'str'

Question

我正在尝试使用熊猫从 excel 文件中读取特定列。当我尝试将这些记录添加到 Solr 时，得到了 TypeError。

我正在使用的代码 -

from __future__ import print_function
import pysolr
import pandas as pd

df_my = pd.read_excel('C:\\Users\\shantanu.nandan\\Desktop\\sample.xlsx',encoding='utf-8')
df_selected = df_my.loc[:,['column_1','column_2','column_3','column_4']]
for index,row in df_selected.iterrows():
    row['column_2']  = row['column_2'].replace('\n','')

for index,row in df_selected.iterrows():
    row['column_2']  = row['column_2'].replace('\r','')

for index,row in df_selected.iterrows():
    row['column_2']  = row['column_2'].replace('<br/>','')

df_dict = df_selected.to_dict('records')
solr = pysolr.Solr('http://localhost:8983/solr/My_Data')
solr.add(df_dict)

放置错误的堆栈跟踪 -
